In Bhagavad-gita (13.3) the Lord says, ksetra jnam capi mam viddhi sarva-ksetresu bharata: O scion of Bharata, you should understand that I am also the knower in all bodies. Every one of us is thinking, I am this body or This is my body, but actually the truth is different. Our bodies are given to us by the supreme proprietor. The living entity, who is also ksetra jna, or the knower of the body, is not the bodys only proprietor; the actual proprietor of the body is the Supreme Personality of Godhead, who is the supreme ksetra jna. For example, we may rent and occupy a house, but actually the owner of the house is the landlord. Similarly, we may be allotted a certain type of body as a facility with which to enjoy this material world, but the actual proprietor of the body is the Supreme Personality of Godhead. He is called sarvadhyaksa because everything in the material world works under His supervision. This is confirmed in Bhagavad-gita (9.10), wherein the Lord says, mayadhyaksena prakrtih suyate sacaracaram: This material nature, working under My direction, O son of Kunti, is producing all moving and unmoving beings. From prakrti, or material nature, come so many varieties of living entities, including aquatics, plants, trees, insects, birds, animals, human beings and demigods. prakrti is the mother, and the Supreme Personality of Godhead is the father (aham bija-pradah pita).
